'l'O ALL PERSONS TO WHOM' THESE'PRESENTS MAY COME:

Be it known that I, DARIUS C. BROWN, oflLowelhiu the county of Middlesex, and State of Massachusetts, have invented anewand useful Improvement in Loom-Harness; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of' which- Figurel denotes a side'elevation,

AFigure Zan end View, and

FigureS a transverse section of a harness-frame provided with myimprovenlent.

After a harness has received a series of warps wound around'a beam, it is customary to fasten or strap the harness to the beam preparatory to the latter and -the harness being introduced into a loom. When the end bars of the harness-frame are practically inelastic, they cause 'the harness, when strapped to the beam, to be i" tangential thereto, and, as a consequence, to inconveniently project therefrom. The harness, when made and Aapplied'to the beam, is apt to be very much in the way, particularly in case of stowage ofthe beam with others.

The object of the invention is to enable the harness-frame, after the h'eddles thereof may have been sup plied with warp-threads, to be bent around the curved surface of the warp-beam, or theivarp 'wound thereon. For this purpose I make the end `connection-bars'of the string-bars of thin iiexile and elastic metalor mate# rial, such as may be bent to conform to the surface-of thewarp-beam or roller, or thatof the warp thereon, and thus not only effect an econoniyofspacewb'ch would otherwise'be taken up by the harness, but enable beams having harnesses so applied to them to be stowed `or packed together ',tovbetter advantage, as the harness will take up less room'than when their end bars-arc inflexible orinelastic.

In the drawings, a and b b are the string-bars, supported by brackets c c and d d, extending from two parallel bars, A B. i l I The beddles made of wire are strung on the bars a, b b inmanner as represented in iig. 3.

The brackets of one bar, A, are connected Wit-h thoseof the other bar, B', by means of two straight elastic metallic strips, C, capable of being bent in an arched or curved form, 4so as tot to the curved surface of a cylinder of war'p when on a Awarp-roller.

The elasticity fof the bars C C should be such that after having been` bent laterally. abouta cylindrical surface, they' will readily recover their straightness, after removal from suchsurface, and previous to the harness being` placed in a loom;

I claim as vmy iuvention- The improved harness or heddle-frame, as made with elastic connection-bars C @substantially-as and for the purpose specified.

I also claim the combination, with the bars A B and brackets, and string-bars supported in such brackets', ofthe elastic connection-bars C C, substantially as herein 'shown and described... l
